In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be described more clearly and more completely with reference to the drawings in the following embodiments, and it is understood that the described embodiments are only a part of the present invention, rather than all of the present invention, and based on the embodiments, other embodiments obtained by those skilled in the art without inventive exercise are within the protection scope of the present invention.
As shown in fig. 1 to 4, a device for flattening tea leaves comprises a frame 1, a reciprocating rotary conveyor belt 2 is installed on the frame 1, a roller 3 for flattening tea leaves is arranged above the conveyor belt 2, the roller 3 and straight rods 22 at two ends of the conveyor belt 2 are synchronously controlled by matching between a gear and a rack, and two compression rollers 37 with elastic adjusting ranges are arranged on two sides of the roller 3 and used for pressing the conveyor belt 2.
The two ends of the conveying belt 2 are provided with rotating drums 21, the rotating drums 21 are sleeved on the straight bars 22 through bearings, the two ends of the straight bars 22 slide in the sliding grooves 11 in the inner wall of the rack 1 through first sliding feet 221, one end of one of the rotating drums 21 is in transmission connection with a first motor 24 and a transfer belt wheel 25 through a belt 23, the first motor 24 is fixed on the rack 1, the transfer belt wheel 25 is fixedly connected to second sliding feet 251 through bearings, the second sliding feet 251 slide in limiting grooves 12 formed in the inner wall of the rack 1, and pushing springs 26 are further arranged in the limiting grooves 12. The first motor 24 drives the drum 21 to rotate through the belt 23, and the drum 21 drives the conveyer belt 2 to rotate, so that the conveyer belt 2 rotates in a reciprocating manner, and tea leaves are rolled and pressed in a reciprocating manner below the roller 3. The transfer band pulley 25 that push spring 26 controlled is used for cooperating two straight-bars 22 apart from adjusting, guarantees belt 23 and keeps the state of tightening all the time, makes things convenient for belt 23 to drive rotary drum 21 and rotates.
The roller 3 is sleeved on the rotating rod 31 through a bearing, a third sliding foot 311 is arranged at one end of the rotating rod 31, the third sliding foot 311 slides in the straight groove 14 of the vertical plate 13, the vertical plate 13 is fixed on the rack 1, a first rack 32 is rotatably connected at one end of the rotating rod 31, the first rack 32 is meshed and connected with a first gear 33, and the first gear 33 is fixedly connected to an output shaft of a second motor 34 installed on the rack 1. The roller 3 rolls on the upper surface of the conveyer belt 2, and the roller 3 realizes the rotary rolling of the tea leaves through the reciprocating rotation of the conveyer belt 2. Preferably set up a motor (not shown in the figure) alone on bull stick 31, this motor output shaft drives cylinder 3 and rotates, and the output shaft of this motor still overlaps and is equipped with two connection pieces 36 of free rotation to this motor can cooperate bull stick 31 to go up and down, realizes pressing down of cylinder 3 pivoted control and do not influence connection piece 36 control compression roller 37 to conveyer belt 2.
One end of each of the two straight rods 22 is fixedly connected with a second rack 35, and the two second racks 35 are meshed with the first gear 33 and are respectively located on the upper side and the lower side of the first gear 33.
